The South Korean government's weapons acquisitions office on Tuesday said it was seeking $10.5 billion in 2014 in order to pay for new armaments, including more ballistic missiles, the Yonhap News Agency reported.
The high-altitude missiles will be used as part of the South's evolving "kill chain," a defense system that aims to preemptively neutralize a North Korean ballistic missile attack. Once an imminent North Korean missile launch is detected via a network of remotely-piloted aircraft and surveillance satellites, South Korean missiles and fighter planes would be launched against the threat.
The South Korean military anticipates having the kill chain technology fully operationalized no later than 2020.
The South is planning on purchasing additional Patriot Advanced Capability 2 missiles and enhancing its existing stockpile of PAC-3 interceptors.
